Intelligent Industrial Empire

"Young people, don't have to be too modest." The old man thought that Yun Fei was modest.

According to the current speed of the Jiuyi Research Institute, it is very likely that it will catch up with the level of foreign countries in more than a decade, and it may not be that long.In particular, Yunfei has always invested in these technology developments regardless of cost, which is a condition that no enterprise has.Most foreign companies are joint-stock companies, and every technical investment needs to be authorized by the board of directors. Those shareholders may not invest research funds in projects that do not have much return on investment.

"Father, this is not really modest. The technology research and development area is already difficult, otherwise we have so many domestic companies, so many universities and scientific research institutes for so many decades and have not achieved much." Yun Fei said solemnly.

Why did Taizu let the whole country enter such a state when he was old?

The slogan of catching up with the English Premier League was put forward by Taejo, because he did not know that the improvement of technology was originally a very slow process.What's more, domestic basic conditions are far worse than those abroad.

"This is our test workshop, covering an area of ​​2,000 square meters, 54 CNC machining centers of various types, 39 CNC lathes, and 67 other equipment... Mainly responsible for the precision of all research projects of the entire institute Manufacturing of mechanical parts and undertaking some very precise parts processing. At present, our main customers are our next door Aerospace Group, Rongcheng 132 Factory, Rongcheng Optoelectronics Research Institute, Southwest Nuclear Industry Research Institute and other highly precise research institutes and factories..." The entire test workshop is actually a confidential machining workshop.

This is different from the ordinary precision machining workshop. The Jiuyi Research Institute needs a lot of mechanical parts in the research process. After all, they are single-piece and small-batch production, but except for their own business inside, they are all Super processing for precision mechanical parts.The current manufacturing capacity, technical equipment, manufacturing experience, etc., can be ranked in the whole China.The most ordinary workers are technicians, and senior workers are just apprentices here. The purpose of their existence is to do miscellaneous work and perform preliminary processing of some parts with very demanding precision!

Although this production workshop does not have too many equipment and no more than 200 personnel, its annual output value exceeds 200 million yuan!The biggest customer is the 132 factory. All kinds of test products and all kinds of products that are too difficult to process are thrown into this production workshop originally for testing the performance of the testing equipment for outsourcing processing.

Especially in the aerospace next door, there are a lot of imported equipment in place every year, but they have not been able to get the top foreign processing center. Perhaps their workers are not inferior to the test workshop of the Jiuyi Research Institute, but their equipment But there is no way to compare it with the test workshop of the Jiuyi Research Institute.

The workshop here was originally set up to obtain various data of the machine tool during processing.The most basic of heavy-load cutting tests, repeated positioning accuracy tests, etc., is that there is no need to use such high-precision equipment and such experienced skilled workers.

"Yun Fei, you guys are not willing to give up the processing business for anything!" Aunt Deng laughed when she heard this introduction.

Yun Fei relied on Xinkai to start his business, and Xinkaixing, up to now, has also used machining as its main business, and its annual profit is more than 300 million yuan in net profit.

"Auntie Deng laughed. It's not that I don't want to give up. These devices continuously accumulate processing data during use, so that they can provide the most reliable parameters for the next generation of equipment. All the technologies researched by the research institute, the first It is always tested on these devices, and will be handed over to Jiuyi Research Institute for production after verifying that there are no problems..." Yunfei is still serious.

What is the performance of a piece of equipment, how much the theoretical design is different from the actual one, and how many functions of various designs can be realized, all of which can be obtained during the processing process.Otherwise, the theoretical precision designed is the precision produced by the machine tool, and there is no technical difficulty at all.

"Lao Deng, are you here?" Deng Lanqing and Yun Fei and his father and the group were about to walk into the area of ​​several five-axis machining centers. Sun Lin appeared with a gray head and a thinner person. In front of a group of people.

"Academician Sun, you have created our Chinese own five-axis machining center, so that our country will not be blackmailed by foreign countries on this, it is amazing!" For this young old man who is two rounds younger than him, the old man actually pushed away and helped To his old girl, he bowed deeply to Sun Lin.

This abnormal behavior of the old man made the whole workshop no longer make any noises except for the various harsh noises produced by machine tools.

Many people thought about it at the same time, if in the past few years, the old man might say that he was grateful to this lucky old guy on behalf of the country!

Seeing the old man like this, Sun Lin felt like he was stepped on his aching foot, and he immediately jumped aside. How many people in this country dare to accept the old man's bow?

"Father, this can't be done. This is our job. What's more, we can develop a five-axis CNC machine tool. This is not done by me alone, but by the entire project team, the entire company, and even the country. It came out. I am ashamed to say that the five-axis machining center that we have researched is still too far away from the top foreign equipment..." Sun Lin was burst into tears by his father's behavior.

"Let's go and see what a five-axis machining center looks like!" For this matter, the old man doesn't have much language.

But the tremor in his voice betrayed his excitement at this time.When he was in power, the country's Dongfeng-31 missile, 052 destroyer, Yun-10 aircraft and other national-level strategic projects, all research projects applied to the country for the same equipment-a five-axis linkage processing center!

At that time, China could not even produce three-axis machining centers.

Even if we organize research, it is impossible to solve this problem in a short time.As the supreme leader of the country, the old man has negotiated privately with the Americans and privately with the Japanese. The humiliation in the process is known to the outsiders except those involved.

Many people say that without a five-axis machining center, would we not be able to manufacture it?

Back then, there was no advanced equipment, no technical reserves, or even a supercomputer. Didn’t we also make two bombs and one satellite?

If you use the workers' experience to process them by hand, the most precise parts in the world can be manufactured.For China's two bombs and one star, all precision parts are basically filed deeply with the files in the hands of the top fitters in China.The Hangti 002 base is in the deepest part of Daba Mountain in the most confidential production workshop in China. Basically, there is no equipment. The average age of all workers is over fifty. No one from the outside world knows that these workers have only one equipment. File!

File, this is the top artifact in the machinery manufacturing industry.

In the final processing of a missile air rudder, a nine-level fitter may spend hundreds of man-hours, and then, using a four-axis machining center, it only takes less than six hours!In the manual processing process, as long as any link goes wrong, all the hard work is wasted.But the machining center will not have such problems.As long as there is no problem with the sample processing, all parts can be processed to almost the same size!This is what manpower cannot match.

The more advanced the equipment, the higher the accuracy requirements of key components.

Otherwise, the old man would be so excited?

In the five-axis machining center area, the most marginal is a gantry machining center with two huge columns without a protective cover. The working table below is more than two meters in length and one meter in width.The difference from other processing center of gravity is that the workbench has a huge spherical connection like the link between the bottom ball head of a car transmission control lever and the transmission. With the naked eye, it is far bigger than a person's head. Big.

A small worktable with a diameter of more than half a meter is directly connected to the sphere.

On the workbench, there is a huge shelf. The two ends of the shelf are pressed with a pressure plate to hold a silver-white workpiece with a length of more than 1.8 meters and a width of about 600 millimeters.This is not the most important thing. The important thing is that the part is turning slowly, and the small worktable driven by the spherical connection at the bottom is constantly swinging back and forth. The spindle with the processing tool is also following the workpiece. Flip and change direction...

Seeing this, most people who don't know what this is have grown up their mouths!

"This is our largest experimental five-axis machining center, which has just been transformed from a gantry-type high-speed milling machine. It is currently processing the solid wings of the ARJ-21 that Yanlong Aircraft is about to do in the wind tunnel test. Semi-finishing is currently in progress ......" Sun Lin pointed to the work piece that was constantly rotating, the worktable was constantly oscillating, and the spindle was also constantly moving up and down and the machine tool that was oscillating left and right introduced to everyone.

"This is a five-axis machining center?" The old man's eyes were not very good, but he hurriedly put on the reading glasses hanging around his neck when he saw that the huge machine tool was moving everywhere.

"No, this is a nine-axis five-linkage machine tool based on a five-axis linkage CNC machine tool. The largest workbench below is a part, the upper spindle is a functional part, and the accessories in the middle are also a system. This is just a conceptual model. If you remove the spherical attachment on that part of the workbench, this is just a four-axis gantry machining center..." Sun Lin said proudly.
